Eagles injury report: Chris Polk practices, Josh Huff, Matt Tobin out

PHILADELPHIA -- Eagles running back Chris Polk returned to the practice field for the first time since the early stages of training camp Tuesday at the Novacare Complex.

Polk, who made the roster as the third running back behind LeSean McCoy and Darren Sproles had previously been sidelined with a hamstring injury. His return to practice helps alleviate concerns that the Eagles would enter the opening game against the Jaguars Sunday with only two healthy running backs on the roster.
